It was reported today that Rich Hill is now a free agent. I think that he has enormous potential and is worth at least a minor league deal with an invite to spring training. If he gets his back situation fixed, he could fill a spot nicely in the rotation.
I'm guessing that a lot of teams will go after him, with the potential that he has shown in the past. I'd hate to see the Cardinals get him and then watch Dave Duncan turn him into a 15-18 game winner.
Just think about the following quote from Michael Barrett about Hill which I found on Wikipedia.org:
[Hill's] curveball is so electric that the first couple of times I caught him, I had a tendency to come up on the curve because it bites so much. You just don't see a left-handed curveball like that anymore. When he's good, it doesn't hang, and it's nearly unhittable."
